Investigation of a method for measurement airway wall with 3D-thoracic CT images

Abstract (in Japanese) (See Japanese page) 
(in English) Evaluating airway wall is an important factor for diagnosis of COPD(Chronic Obstructive Pulumonary
Disease) by use of CT (computed tomography) images. COPD is a disease that changes airway wall thickness, and
a diagnosis with evaluating airway wall for it is carried out by a doctor manually by use of each two-dimensional
CT slice image. However, we consider the three-dimensional evaluation of airway wall thickness is more effective for
accurate COPD diagnosis. And that airway wall is consisted of two factors; one is airway wall area (outer wall area) and the other is inside area (inner wall area). So we must detect outer wall area and inner wall area to evaluate them automatically. In this paper, we propose a method for analyzing air area (inner wall area) and wall area (outer wall area). Especially, there are unwanted objects like vessels around the outer wall in clinical three dimensional thoracic CT images. So we propose a evaluating method to analyze them and checked a method by use of phantom data.
